  text: Zygotic genome activation (ZGA) initiates regionalized transcription underlying
    distinct cellular identities. ZGA is dependent upon dynamic chromatin architecture
    sculpted by conserved DNA-binding proteins. However, the direct mechanistic link
    between the onset of ZGA and the tissue-specific transcription remains unclear.
    Here, we have addressed the involvement of chromatin organizer Satb2 in orchestrating
    both processes during zebrafish embryogenesis. Integrative analysis of transcriptome,
    genome-wide occupancy and chromatin accessibility reveals contrasting molecular
    activities of maternally deposited and zygotically synthesized Satb2. Maternal
    Satb2 prevents premature transcription of zygotic genes by influencing the interplay
    between the pluripotency factors. By contrast, zygotic Satb2 activates transcription
    of the same group of genes during neural crest development and organogenesis.
    Thus, our comparative analysis of maternal versus zygotic function of Satb2 underscores
    how these antithetical activities are temporally coordinated and functionally
    implemented highlighting the evolutionary implications of the biphasic and bimodal
    regulation of landmark developmental transitions by a single determinant.

  text: Cell-cell contact formation constitutes an essential step in evolution, leading
    to the differentiation of specialized cell types. However, remarkably little is
    known about whether and how the interplay between contact formation and fate specification
    affects development. Here, we identify a positive feedback loop between cell-cell
    contact duration, morphogen signaling, and mesendoderm cell-fate specification
    during zebrafish gastrulation. We show that long-lasting cell-cell contacts enhance
    the competence of prechordal plate (ppl) progenitor cells to respond to Nodal
    signaling, required for ppl cell-fate specification. We further show that Nodal
    signaling promotes ppl cell-cell contact duration, generating a positive feedback
    loop between ppl cell-cell contact duration and cell-fate specification. Finally,
    by combining mathematical modeling and experimentation, we show that this feedback
    determines whether anterior axial mesendoderm cells become ppl or, instead, turn
    into endoderm. Thus, the interdependent activities of cell-cell signaling and
    contact formation control fate diversification within the developing embryo.

  text: During metazoan development, the temporal pattern of morphogen signaling is
    critical for organizing cell fates in space and time. Yet, tools for temporally
    controlling morphogen signaling within the embryo are still scarce. Here, we developed
    a photoactivatable Nodal receptor to determine how the temporal pattern of Nodal
    signaling affects cell fate specification during zebrafish gastrulation. By using
    this receptor to manipulate the duration of Nodal signaling in vivo by light,
    we show that extended Nodal signaling within the organizer promotes prechordal
    plate specification and suppresses endoderm differentiation. Endoderm differentiation
    is suppressed by extended Nodal signaling inducing expression of the transcriptional
    repressor goosecoid (gsc) in prechordal plate progenitors, which in turn restrains
    Nodal signaling from upregulating the endoderm differentiation gene sox17 within
    these cells. Thus, optogenetic manipulation of Nodal signaling identifies a critical
    role of Nodal signaling duration for organizer cell fate specification during
    gastrulation.

  text: 3D amoeboid cell migration is central to many developmental and disease-related
    processes such as cancer metastasis. Here, we identify a unique prototypic amoeboid
    cell migration mode in early zebrafish embryos, termed stable-bleb migration.
    Stable-bleb cells display an invariant polarized balloon-like shape with exceptional
    migration speed and persistence. Progenitor cells can be reversibly transformed
    into stable-bleb cells irrespective of their primary fate and motile characteristics
    by increasing myosin II activity through biochemical or mechanical stimuli. Using
    a combination of theory and experiments, we show that, in stable-bleb cells, cortical
    contractility fluctuations trigger a stochastic switch into amoeboid motility,
    and a positive feedback between cortical flows and gradients in contractility
    maintains stable-bleb cell polarization. We further show that rearward cortical
    flows drive stable-bleb cell migration in various adhesive and non-adhesive environments,
    unraveling a highly versatile amoeboid migration phenotype.
